Fish are sentient animals who form friendships, experience “positive emotions” and have individual personalities.
That, according to the Royal Society for the Prevention of Cruelty to Animals (RSPCA), is the implication of a landmark new study which found zebrafish are social animals in a similar way to humans and other mammals.
And people who refuse to eat meat on moral grounds but do eat fish – as well as people who keep fish as pets – should bear that in mind, Dr Penny Hawkins, head of the RSPCA’s research animals department, told The Independent.
